One day every human on the world suddenly receives a mail claiming to enact the World Salvation Project. Half in doubt Kurosaki Shion, a diligent university student and loner, follows the mail’s instructions, becoming one of a million Demon Kings governing his very own Domain in the new world.

*** This is a post-apocalyptic story containing many fantasy elements. It is a somewhat dark tale following Shion as he grows while aiming for the unification of the all too sudden new world. It has many game-elements bolstered by strategical thinking while at the same time providing funny moments and romantic encounters.

At level 2, most people unlocked their first talent; those who didn’t were considered fortunate, as they had the potential to unlock rarer talents requiring higher levels. The world’s most rare and powerful talents were revealed at level 5. But what if someone didn’t obtain a talent? Luck quickly turned to misfortune as they were labeled talentless, with no hope of gaining a talent. Sol was one such person who was unable to unlock his talent, but he refused to give up. He persistently fought and trained every day, slowly increasing his level despite the disadvantage in skills. He held onto the hope that, one day, he would be bestowed with a talent like everyone else. As years passed, his determination began to wane until one fateful day. You have leveled up! +5 Free stats. Talent Unlocked - [Siphoner]! This event marked the beginning of his story.
